Structure Init

With this function block it is possible to create a user defined data structure and provide them for further use in the program.

All basic elements are combined in one structure and provided at output Y as data type. Through the inputs, initial values can be assigned to all basic elements. It is possible to provide up to eight input signals for initialization of the data structure.


The data type can be selected in the parameter dialog. By right-clicking into the dialog area, it is possible to add elements to the structure, which creates a new input for that item.


Name I/O Typ(en) Funktion
X0 I Data type independent Items of the data structure
X7 I Data type independent Items of the data structure
Y O User defined data type Data structure




In Online mode the items are set one by one, starting with the one on top. If the same item is defined for different inputs, the last assignment overwrites the ones before.

Pay attention to the sequence of the block numbers.


The following example shows how to create and initialize a user defined data structure which is then used by further function blocks.
